Is it possible to have a line segment with: [tex]m = \infty[/tex]

To answer this question, we will interpret the steepness as slope.

So, we have:

[tex]m = \infty[/tex]

The interpretation of a line with: [tex]m = \infty[/tex] is:

It starts from (x,y_1) and ends at (x,y_2)

When the slope (m) is then calculated, we have:

[tex]m = \frac{y_2 - y_1}{x_1 - x_1}[/tex]

[tex]m = \frac{y_2 - y_1}{0}[/tex]

[tex]m = \infty[/tex]

What this means is that, the line has no end points.

A line segment as described here means a line that has endpoints (i.e. a finite starting point and a finite finish point)

So, we've established that: [tex]m = \infty[/tex] means no endpoints and a line segment has end points, then we can conclude that it is not possible to create a line segment with [tex]m = \infty[/tex]

Steepness of a  line is the rise or fall of it at a sharp angle.The Is it not possible to create a line segment with infinite steepness, as the slope of the such line will be infinite whether a line is plotted with finite points.

Steepness of a  line is the rise or fall of it at a sharp angle. The slope of the line describe the steepness of a line.

A infinite steepness refers to a vertical line on the graph. When the line with infinite steepness plotted on the graph it is only parallel to the y axis. The change on the x axis is zero and does not move in the x axis, when a line has infinite steepness.

To understand it better suppose a line is passed through the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] points. For such line the slope of the line can be given as,

[tex]m=\dfrac{y_2-y_1}{x_2-x_1} [/tex]

The line with infinite steepness does not move in the x axis. The coordinate of the x axis same for the line. Thus,

[tex]x_2=x_1[/tex]

The slope for such line is,

[tex]m=\dfrac{y_2-y_1}{x_1-x_1} [/tex]

[tex]m=\dfrac{y_2-y_1}{0} [/tex]

[tex]m=\infty[/tex]

Thus the slope of the line is infinite. But the line With no finite point is not possible to plot.

Hence the Is it not possible to create a line segment with "infinite steepness, as the slope of the such line will be infinite whether a line is plotted with finite points.

Answer:

75th term in the sequence is 227.

Step-by-step explanation:

75 term of A.P is

a_75= a+ (n-1)d

Given series is 5,8,11,14.

hence a= 5 d= 8-5 = 3 , a_75.

a_75 = 5+(75-1)3

= 5+ (74)3

= 5 +(222)

= 227

The value of 75th term in the sequence is,

⇒ a₇₅ = 227

An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.

We have to given that;

The first four terms of an arithmetic sequence are,

⇒ 5, 8, 11, 14

Here, We have;

First term (a) = 5

Common difference = 8 - 5 = 3

Hence, The value of 75th term in the sequence is,

⇒ a₇₅ = a + (n - 1) d

⇒ a₇₅ = 5 + (75 - 1) 3

⇒ a₇₅ = 5 + 222

⇒ a₇₅ = 227

Thus, The value of 75th term in the sequence is,

⇒ a₇₅ = 227

Answer:

1) yes, all of their angles are equal.  (75°, 45°, and 60°)

2) No, their angles are not equal. (42°, 48°, 90°  vs  58°, 32°, 90°)

Step-by-step explanation:

1.

ΔWXY and ΔRST are similar because they have equal angles.

2.

ΔJKM and ΔKLM are not similar because the angles are not equal.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

1.

In ΔWXY,

∠X = 75

∠Y = 60

∠W = 180 - (75 + 60) = 180 - 135 = 45

In ΔRST,

∠S = 45

∠R = 60

∠T = 180 - (45 + 60) = 180 - 105 = 75

Now,

We can say that,

ΔWXY and ΔRST are similar because they have equal angles.

2.

In ΔJKM,

∠J = 42

∠M = 45

∠K = 180 - (42 + 45) = 180 - 87 = 93

In ΔKLM,

∠K = 58

∠M = 90

∠L = 180 - (58 + 90) = 180 - 148 = 132

ΔJKM and ΔKLM are not similar because the angles are not equal.

Thus,

ΔWXY and ΔRST are similar because they have equal angles.

ΔJKM and ΔKLM are not similar because the angles are not equal.

Step-by-step explanation:

Answer:

45 min = 0.75 hours

Step-by-step explanation:

Since Boat A is 6 miles ahead of boat B and has a top speed of 36 miles per hour, the distance it moves in time, t is d = 6 + 36t where 36t is the distance it moves in time, t with speed 36 miles per hour.(36t = 36 miles per hour × t hours)

Also, since Boat B has a top speed of 44 miles per hour, the distance d' it moves in time, t with this speed is

d'= 44t (44t = 44 miles per hour × t hours)

When Boat B catches up with Boat A, their distances are equal. So,

d = d'

6 + 36t = 44t

subtracting 36t from both sides, we have

44t - 36t = 6

simplifying

8t = 6

dividing through by 8, we have

t = 6/8 hours

t = 0.75 hours

t = 0.75 × 60 min

t = 45 min

Answer:

Answer in explanation

Step-by-step explanation:

The graph of f does not cross the x-axis. We know this because for any value x, we always get that x^2+4 is positive. x^2 is positive or zero ( 0 or greater than 0) for any x but adding 4 to it makes It 4 or greater than 4.

The discriminant is negative.

That is, b^2-4ac is negative.

Upon comparing ax^2+bx+c to x^2+4 we see that a=1, b=0, and c=4..

Plugging those into b^2-4ac gives

(0)^2-4(1)(4)

=0-16

=-16.

Negative discriminant implies two nonreal zeros so it will not cross the x-axis.

(Positive discriminant implies 2 real and zero discriminant imples 1 real.)

f(x)=-5x2+4x-6

f(2)= -5*2*2+4*2-6

f(2)= -20+2
